I'm installing a Snow Performance Stage II MAF water/meth kit on my DASC'd Z3. I'm trying to find which of the four wires running to the MAF (HFM) is the signal wire. I'm 99% sure that the wire colors on the 318ti MAF wiring harness are the same as my Z3 as they share the same motor, DME, etc.

The wire colors are:
1. Brown
2. Red with white stripe
3. White with violet stripe
4. White with blue stripe

Does anyone know which of these is the 0-5 volt MAF signal wire?

Thanks,
Christian
